The Effects of Working While in School: Evidence from Employment Lotteries
利用乌拉圭一项随机分配工作机会的工读项目数据，研究发现参与者在项目结束两年后收入提高8%，且工作技能培养是主要机制。
Does working while in school smooth students’ transition into the labor market? We provide evidence on this question by leveraging a one-year work-study program that randomized job offers among over 90,000 student applicants in Uruguay. Program rules forbade employers from employing participants in the same job after program completion, and less than 5 percent of participants ever worked in the same firm again. Two years after the program, participants had 8 percent higher earnings. Our results suggest that the program’s focus on work-related skills was a key mechanism for earnings impacts.
